High availability power solutions specialist MGE UPS Systems has today announced the launch of the Galaxy 5000 and Galaxy 6000 UPS systems to provide continuity of service for critical installations such as data centres, industrial processes and telecommunications.
The Galaxy 5000, available in 20, 30, 40, 60, 80, 100 and 120 kVA, is the latest of six generations of high performance, three phase UPSs. It features an on-line double-conversion architecture with a variable switching frequency SixPack IGBT inverter technology (THDU less than 2%). SixPack IGBTs are also used at the UPS input stage to provide a clean input current waveform to ensure that they can be built into any electrical installation without interference. Galaxy 5000 has been designed to support leading power factor servers such as Blade Centres.
The Galaxy 5000 is modular and can be upgraded to meet the changing requirements of sites and critical applications. The basic rating can be increased 6-fold and it can be used in conjunction with static transfer switches (STS) to provide redundant electrical power supplies. Backup times from 5 minutes to 8 hours are available as standard to meet various requirements.
The clean input current waveform provided by the SixPack technology means that the mains supply does not need to be oversized, which can result in considerable savings. Its operating efficiency can be up to 94%, which can save 1,777 to 8,800 of electricity per year (1,777 for a load of 100 kW to more than 8,800 for a load of 500 kW).
The Galaxy 6000, available in 250, 300, 400, 500, 600 and 800 kVA, features the very high availability power, flexibility and low cost of ownership of the Galaxy 5000 with an icon-based graphical user interface for ease of operation. Its large touchscreen colour display provides access to all the information essential for managing the high availability power supply including metering, alarms, statistics and event log.
"Four basic factors must be taken into account when selecting an uninterruptible power supply: the quality of the power, flexibility, ease of use and total cost of ownership," explains Darrell Smithson, Sales Director for MGE. "For mission-critical applications, the stakes are such that it is absolutely essential to offer operations managers systems that provide the most effective combination of these factors, regardless of the complexity of the environments and conditions. This is the reasoning behind the innovations we have incorporated in the Galaxy 5000 and 6000."
